To promote her spring collection, Rachel Antonoff recruited pal Alia Shawkat (who's already starred in one of Rachel's campaigns) and brother Jack--who's in the bands Steel Train and Fun, which was recently profiled by our Music Blogger) for a video look book that's as much an homage to 80's teen flicks as it is the designer's girly vintage style. In the video, the two reenact a scene from the cult classic Teen Witch--which starred Robyn Lively (Yes, Blake's real-life sister!) as the titular heroine who uses her sorceress skills to become the most popular girl in school--specifically, the hilarious rap battle that takes place in the film. Clearly, we're fans of both Rachel and pre-HSM teen movie musicals, so while we wait for the video to debut, these behind-the-scenes photos will suffice. (And if you don't know what we're talking about, you must read on and watch the awesomeness that is the video after the jump.)
